Among many outstanding Restek colleagues and partners, our own Jack Cochran is an invited speaker for the Thermo Fisher Scientific Dioxins & POPs seminars:

Front End Alignment, It’s Not Just for Automobiles: Optimizing the GC for GC-MS Analysis of Environmental Compounds
Session: Dioxins & POPs: Discover the Most Comprehensive GC-MS Portfolio and Complete Analysis Workflows
Sunday, August 28, 13:30–17:00
Sala Onice | Firenze Fiera – Congress and Exhibition Center | Piazza Adua, 1 – 50123 Firenze
Jack Cochran, Restek Corporation

Jack is also presenting during Thursday’s abstract session:

Gas Chromatography – Atmospheric Pressure Ionization Mass Spectrometry with Helium and Nitrogen Carrier Gases for Fast Analysis of Brominated Diphenyl Ethers
Session: New Methods of Analysis
Thursday, September 1, 10:45–11:00, Michelangelo Auditorium
Jack Cochran, Restek Corporation

Jack Cochran is a recognized expert in GC and GCxGC for the analysis of pesticides and priority pollutants in food, soils, sediments, air, water, and other matrices. He uses his years of real-world experience in method development, sample preparation, and analysis to help chromatographers worldwide and is still a “hands on” scientist, spending as much time in the laboratory as possible. His presentation at Dioxin 2016 is sure to be valuable for attendees.

Restek Graduates Another LCC Student.


Sara with her son, Caleb, at LCC graduation

Congratulations to Sara Eyster on joining a long list of Leadership Centre County (LCC) alumni from Restek! Sara has been with Restek for nearly 14 years, and in her current position as a Quality Systems Administrator III, she helps to ensure ISO control and the product quality that you’ve come to rely on from Restek as part of her document control, internal auditing, and vendor auditing responsibilities.

Like Restek, LCC is dedicated to the concept of “servant leadership” and educates participants regarding the needs, available services, strengths, opportunities, and current issues in the Centre County community. Community leaders share their experiences with LCC students to improve their skills in order to increase the county leadership pool with people who are well-informed, networked, and qualified to lead. As evidence of the program’s value, several Restek-sponsored LCC graduates have gone on to leadership positions within Restek. For more information on LCC go to 

Analysis of Gases via Gas Chromatography: Part 3: CO and CO2

CO and CO2 are products that are present in many industrial processes. CO2 is used in many applications varying from propellants, refrigerants, preservatives, beverages, inert atmosphere, and fire extinguishers. It’s also used in oil recovery, supercritical solvent, and greenhouse analysis. Carbon dioxide is analyzed typically at higher levels (10 ppm – % level). CO is a toxic gas, but it is used mostly used as chemical precursor. Both CO and CO2 are analyzed at levels from 100 ppb to % level. Because these gases cannot be detected by FID, other detectors are required. One can also convert the CO/CO2 into methane to take advantage of FID sensitivity.
